Although Rodger Bumpass got his start in Hollywood as a minor character actor on sophomoric comedies such as National Lampoon's cable TV special "Disco Beaver from Outer Space," he is better known in the industry as a voice actor for animated films and TV shows. After attending Arkansas State University, he began writing and performing in a late-night comedy show on local ABC affiliate KAIT-TV during the 1970s, then graduated to a touring production of the National Lampoon comedy revue "That's Not Funny, That's Sick" and the then-red hot humor magazine's 1978 TV movie "Disco Beaver from Outer Space." The facility Bumpass showed in these venues for a variety of silly voices were then put in a much more family-friendly context when he began working as a cartoon voice actor in the early 1980s. His best known voiceover roles are as the terminally grumpy Squidward Tentacles on the hit children's series "SpongeBob SquarePants" and as brainiac inventor Professor Membrane on the Nickelodeon program "Invader ZIM."
